The features and benefits of Power-Tech Absorbent Glass Mat Technology
using Sealed-valve-regulated construction are many. High discharge rates from Low internal
resistance , they also have great vibration and shock characteristics from their tight
construction Highly porous microfiber glass separators completely wrap around the positive
plate to absorb and immobilise the electrolyte; These allow the Oxygen formed at the
positive plate to react with Hydrogen from the negative plate to recombine as water
for the electrolyte. They have enough electrolyte for their entire usable life
and should not be opened. By design, AGM's low gassing
characteristics mean there are no special ventilation requirements for Power-Tech AGM's in
normal use. Like Deka Gels, simple ambient air flow through limber holes or air-slots are sufficient.
Position independent, Power-Tech AGM's may be installed and secured pretty much
anywhere except upside down. Consistent Quality Certifed to ISO 9001 and a UL
recognised component, (MH17218).

Charging: Use a good constant potential, voltage-regulated charger. For 12 volt
batteries charge to at least 14.4v- but no more than 14.6v @ 68°F. Remember; Under or
overcharging will shorten any batteries life. For ease of use, the majority of the
top quality inverters/chargers already have an AGM charge setting programmed in so the
transition to AGM's from conventional flooded batteries or is very straight-forward.

MG notes that the very high internal gas recombination of - Absorbent Glass Mat
Separator Starved Electrolyte type Batteries (known as the AGM type) -
approaches 99%. This gas recombination produces internal heat (exothermic).
Simply put there is very little electrolyte to help cool the unit through
the battery case walls; Therefore please follow the
Voltage/Temperature guidelines below for maximum use and life.
